Thanks for the info dmax the codes where bank 1 sensor and fuel trim bank 1? I'll try find the leak and post update of how i get on.

Hmmm? I recall reading once or twice how an air leak affected only one bank...thought it was odd...but for some reason I'm vaguely remembering either TB or DISA issue. I could be wrong, of course, but you'll hopefully find something by spraying around.

There's a port on back of intake you can plug a hose into and blow smoke in...like from a cigar for a total diy smoke test. Just plug the intake boot after the maf.

GL!
